Cellulose ether is a versatile, high-performance polymer derived through etherification of cellulose, the natural polysaccharide found in plant cell walls. As a family of water-soluble derivatives—including HPMC (hydroxypropyl methyl cellulose), HEC (hydroxyethyl cellulose)—it serves as a backbone in modern industrial formulations. With properties such as powerful thickening, water retention, film-forming, and rheology modification, cellulose ethers have become indispensable in construction, paints & coatings, pharmaceuticals, personal care, ceramics, and oilfield drilling.
According to industry reports, the global cellulose ether market size exceeded $5.2 billion USD in 2023 and is projected to grow at a CAGR of 4.5% from 2024 to 2030—demonstrating its pivotal role in sustainable material solutions, especially in green construction and eco-friendly formulation trends.

Film-forming | Excellent | Good | Poor | Very good |
For key technical difference between cellulose ether products, note: The degree of substitution (DS), viscosity range, and purity are determinative of suitability for specialized industries. HPMC tailored for tile adhesives, mortars or paint have unique methoxy:hydroxypropoxy ratio (typically: 19–24% methoxy, 4–12% hydroxypropoxy), giving high water retention and open time for construction needs.
